Hi Aaron: thanks. I tried the security definer. it works well as follows : CREATE FUNCTION kill_process(integer) RETURNS boolean AS 'select pg_cancel_backend($1);' LANGUAGE SQL SECURITY DEFINER;
---- One more question about this function : if non-super user get the execute this function, he/her will have privilege to kill all the processes which belong to the postgresql process. How can we avoid that happing. Thanks.
